Edgewise for sure but that's not So. Vt.
My rec is Totem Pole in Ludlow. You need to specify your angles. Also specify you do not want tip/tails dulled. Just to make sure. If you specify angles, it's unlikely you'd get that but I can't tell you the number of skis I've seen where this has been done by "good" shops on non race skis.
There's several structures you can choose from. You also need to decide if you want a "radial" tune. That is where there's more base bevel in tips/tails than underfoot. You can do .5, .75 underfoot and then more for tip/tail. Usually .25 degrees.
Talk to Toren he's the co owner and runs the shop with the $350k robotic machine.
If you're going to Killington it would be Peak Performance, but it's been years since I've dealt with them.
